Look up year 536 (also known as "the worst year to be alive")Appropriately, all I get is a black screen with a message saying "This video is not available in your country."
Since no clue is offered as to the subject of this thread, I am none the wiser.
Historical information of possible interest? How many people know the real story and full scope of this minor "extinction" event?Right so there is evidence of a volcanic winter in 536 and for perhaps a couple of years afterwards. What is the discussion topic?
https://en.wikipedia.org/wiki/Volcanic_winter_of_536Scientific evidence[edit]
Tree ring analysis by the dendrochronologist Mike Baillie, of the Queen's University of Belfast, shows abnormally little growth in Irish oak in 536 and another sharp drop in 542, after a partial recovery.[20] Ice cores from Greenland and Antarctica show evidence of substantial sulfate deposits in around 534 ± 2, which is evidence of an extensive acidic dust veil.[21]
It was not an extinction event.Historical information of possible interest? How many people know the real story and full scope of this minor "extinction" event?
It is also a cautionary tale.

Who is making this claim? The Wiki article associates the claim it was Krakatoa with somebody called David Keys, but says he had to shift the date of contemporary documents by over a century to make it fit, and that drilling in the Sunda Strait rules out an eruption at the time in question. So it seems to be balls.TRANSCRIPT: "Krakatoa is now the most likely culprit. The volcano that did go up in 535 A.D would have produced a dust cloud that enveloped the world. It would have been one of the most dangerous spectacles ever seen. A 30-mile high column of ash and dust brought global climatic catastrophe. Darkness drought frost and famine and ultimately chaos and war. It was a natural catastrophe that would change the course of human history."
So one opener to a discussion stems from the question: "Why is this in Biology & Genetics, rather than Earth Science (or even History)"?
Would a clarification for that result in the offshoot of another query? Future developments will tell.

Yes I read that. He's an archaeologist and has done some good work. But he is not a volcanologist or geologist. He should let those specialists advise him on what mountain it could have been, while he focuses on the effects on human history - which could have been dramatic and important.Granting that this video is not much older than the date of its YouTube release, I can't find anything new published in 2022 or 2023 that has countered the conclusion that it was not caused by Krakatoa.
I haven't had free time to watch the whole 99-minute video any more than probably anyone else has (apart from maybe Write4U), but judging from that area of the transcript, it really does seem to be advocating Keys' overall claims (which includes that the event ended ancient civilization and started the medieval era).
So while a climatic disturbance of some kind (volcanic in origin or otherwise) seems vouched by the majority to have occurred circa that period of the past, this video's choice of the culprit and its historical theories doesn't seem to be a blue-ribbon account of it.
